Description
1 L'invention concerne un procédé de réalisation d'une matelassure de véhicule automobile et une matelassure obtenue par un tel procédé. The invention relates to a method for producing a motor vehicle cushioning and a padding obtained by such a method.
Il est connu de mettre en oeuvre un procédé de réalisation d'une matelassure de véhicule automobile, ladite matelassure comprenant un complexe de revêtement et un bloc de rembourrage en mousse élastiquement compressible, ledit complexe comprenant une couche inférieure d'étanchéité à la mousse surmoulée par ledit bloc, ladite couche d'étanchéité comprenant un orifice de ventilation du passager, ledit bloc comprenant un conduit de ventilation débouchant sur ledit orifice, ledit procédé comprenant les étapes suivantes : • prévoir un moule comprenant une cuve et un couvercle définissant un espace de moulage de ladite matelassure, ledit couvercle comprenant un plot de moulage dudit conduit, • disposer ledit complexe dans ladite cuve, • fermer ledit couvercle de sorte que l'extrémité libre dudit plot prenne appui sur la périphérie dudit orifice en créant une étanchéité dudit orifice par rapport à la mousse, • injecter un mélange précurseur de mousse élastiquement compressible dans ledit espace de moulage, • après expansion de la mousse, démouler la matelassure obtenue. It is known to implement a method of producing a motor vehicle cushioning, said cushioning comprising a coating complex and an elastically compressible foam padding block, said complex comprising a lower foam sealing layer overmolded by said block, said sealing layer comprising a passenger ventilation port, said block comprising a ventilation duct leading to said orifice, said method comprising the following steps: • providing a mold comprising a tank and a lid defining a molding space said padding, said cover comprising a molding pad of said pipe, • arranging said complex in said tank, • closing said lid so that the free end of said pad bears on the periphery of said orifice by sealing said orifice relative to to the foam, • inject a precursor mixture of foam being elastically compressible in said molding space; after expansion of the foam, demolding the padding obtained.
Une telle réalisation peut présenter divers inconvénients : • dans le cas d'un complexe d'épaisseur inférieure à son épaisseur nominale, il existe un risque de fuite de mousse dans l'orifice puisque l'extrémité libre du plot prend imparfaitement appui sur la périphérie de l'orifice, • dans le cas d'un complexe d'épaisseur supérieure à son épaisseur nominale, il existe un risque de défaut d'aspect de la matelassure qui peut présenter un bossage à l'aplomb de l'orifice, ceci dans la mesure où le plot vient sur-compresser le complexe au niveau de l'orifice, le complexe créant un bossage localisé lorsqu'il n'est plus sous contrainte dans le moule, • dans le cas où le plot est un peu décalé radialement ù en référence au plot ù par rapport à l'orifice, il existe un risque de fuite de mousse dans l'orifice puisque l'extrémité libre du plot risque de ne pas être en appui sur toute la périphérie de l'orifice. L'invention a pour but de pallier ces inconvénients. Such an embodiment may have various drawbacks: in the case of a complex with a thickness less than its nominal thickness, there is a risk of foam leakage in the orifice since the free end of the stud imperfectly bears on the periphery of the orifice, • in the case of a complex of thickness greater than its nominal thickness, there is a risk of lack of appearance of the padding which may have a boss in line with the orifice, this in the extent to which the stud over-compresses the complex at the orifice, the complex creating a localized boss when it is no longer under stress in the mold, • in the case where the stud is a little offset radially ù with reference to the pad ù with respect to the orifice, there is a risk of foam leakage in the orifice since the free end of the stud may not be supported on the entire periphery of the orifice. The invention aims to overcome these disadvantages.
A cet effet, et selon un premier aspect, l'invention propose un procédé de réalisation d'une matelassure de véhicule automobile, ladite matelassure 10 comprenant un complexe de revêtement et un bloc de rembourrage en mousse élastiquement compressible, ledit complexe comprenant une couche inférieure d'étanchéité à la mousse surmoulée par ledit bloc, ladite couche d'étanchéité comprenant un orifice de ventilation du passager, ledit bloc comprenant un conduit de ventilation débouchant sur ledit orifice, ledit procédé comprenant les 15 étapes suivantes : • prévoir un moule comprenant une cuve et un couvercle définissant un espace de moulage de ladite matelassure, ledit couvercle comprenant un plot de moulage dudit conduit, • prévoir une rondelle d'étanchéité en matériau élastiquement 20 compressible, ladite rondelle présentant un trou de section similaire à celle de l'extrémité libre dudit plot et une enveloppe périphérique englobant celle dudit orifice, • enfoncer ladite rondelle sur ladite extrémité, ladite rondelle saillant axialement ù en référence à l'axe du plot ù au delà de ladite extrémité, 25 • disposer ledit complexe dans ladite cuve, • fermer ledit couvercle de sorte que ladite rondelle prenne appui sur la périphérie dudit orifice en créant une étanchéité dudit orifice par rapport à la mousse, • injecter un mélange précurseur de mousse élastiquement compressible 30 dans ledit espace de moulage, • après expansion de la mousse, démouler la matelassure obtenue.5 L'utilisation d'une rondelle d'étanchéité selon les modalités sus explicitées permet de résoudre les inconvénients de l'état de la technique : • dans le cas d'un complexe d'épaisseur inférieure à son épaisseur nominale, la rondelle saillant axialement au delà de la première extrémité du plot vient combler l'espace entre ledit plot et l'orifice de ventilation, ce qui crée étanchéité à la mousse, • dans le cas d'un complexe d'épaisseur supérieure à son épaisseur nominale, la rondelle se comprime en lieu et place du complexe, ceci dans la mesure où la portance de la rondelle est inférieure à celle du complexe, comme on le décrira plus loin, ce qui évite le risque de bossage créé par libération de la contrainte sur ledit complexe telle qu'observée dans l'art antérieur, • dans le cas où le plot est un peu décalé radialement par rapport à l'orifice, la rondelle, présentant une enveloppe périphérique englobant celle de l'orifice, comble l'espace qui pourrait apparaître entre le plot et l'orifice et fait étanchéité à la mousse. For this purpose, and according to a first aspect, the invention provides a method for producing a motor vehicle cushioning, said cushioning comprising a coating complex and an elastically compressible foam padding block, said complex comprising a lower layer foam sealant overmolded by said block, said sealing layer comprising a passenger ventilation port, said block comprising a ventilation duct leading to said orifice, said method comprising the following steps: • providing a mold comprising a tub and a lid defining a molding space of said padding, said lid comprising a molding pad of said duct, • providing a sealing washer of elastically compressible material, said washer having a hole of section similar to that of the end free of said pad and a peripheral envelope encompassing that of said orifice • pushing said washer onto said end, said washer projecting axially with reference to the axis of the stud beyond said end, arranging said complex in said tank, closing said lid so that said washer bears on the periphery of said orifice by creating a seal of said orifice relative to the foam, • injecting a precursor mixture of elastically compressible foam 30 in said molding space, • after expansion of the foam, demolding the padding obtained.5 The use of a sealing washer according to the above-mentioned methods makes it possible to solve the disadvantages of the state of the art: • in the case of a complex of thickness less than its nominal thickness, the washer projecting axially beyond the first end the pad fills the space between said stud and the ventilation opening, which creates foam-tightness, • in the case of u n complex thickness greater than its nominal thickness, the washer is compressed instead of the complex, this insofar as the lift of the washer is less than that of the complex, as will be described later, which avoids the boss risk created by release of the stress on said complex as observed in the prior art, • in the case where the pad is slightly offset radially from the orifice, the washer, having a peripheral envelope including that of the orifice, fills the space which could appear between the stud and the orifice and makes sealing with the foam.
Selon un deuxième aspect, l'invention propose une matelassure obtenue par un tel procédé. According to a second aspect, the invention proposes a padding obtained by such a method.
D'autres particularités et avantages de l'invention apparaîtront dans la description qui suit, faite en référence aux figures jointes dans lesquelles : • la figure 1 est une représentation schématique en coupe partielle et en perspective d'une matelassure selon une première réalisation, montrant en outre une rondelle en perspective, • la figure 2 est une représentation schématique en coupe partielle et en perspective d'une matelassure selon une deuxième réalisation, montrant en outre une pluralité de rondelles en perspective reliées entre elles pour former une plaque, • la figure 3 est une vue schématique en coupe partielle de la matelassure de la figure 1 en position dans le moule avant démoulage, dans les cas d'un complexe d'épaisseur inférieure à son épaisseur nominale (figure 4 3a), d'un complexe d'épaisseur supérieure à son épaisseur nominale (figure 3b) et où le plot est décalé radialement par rapport à l'orifice (figure 3c). Other features and advantages of the invention will appear in the description which follows, with reference to the appended figures in which: FIG. 1 is a schematic representation in partial section and in perspective of a padding according to a first embodiment, showing furthermore, a perspective washer; FIG. 2 is a diagrammatic representation in partial section and in perspective of a cushioning according to a second embodiment, further showing a plurality of perspective washers interconnected to form a plate; FIG. 3 is a diagrammatic view in partial section of the padding of FIG. 1 in position in the mold before demolding, in the case of a complex of thickness less than its nominal thickness (FIG. 43a), of a complex of thickness greater than its nominal thickness (Figure 3b) and wherein the pad is offset radially relative to the orifice (Figure 3c).
En référence aux figures, on décrit un procédé de réalisation d'une matelassure 1 de véhicule automobile, ladite matelassure comprenant un complexe 2 de revêtement et un bloc 3 de rembourrage en mousse élastiquement compressible, ledit complexe comprenant une couche inférieure d'étanchéité 4 à la mousse surmoulée par ledit bloc, ladite couche d'étanchéité comprenant un orifice 5 de ventilation du passager, ledit bloc comprenant un conduit 6 de ventilation débouchant sur ledit orifice, ledit procédé comprenant les étapes suivantes : • prévoir un moule comprenant une cuve et un couvercle définissant un espace de moulage de ladite matelassure, ledit couvercle comprenant un 15 plot 7 de moulage dudit conduit, • prévoir une rondelle 8 d'étanchéité en matériau élastiquement compressible, ladite rondelle présentant un trou 9 de section similaire à celle de l'extrémité libre 10 dudit plot et une enveloppe périphérique englobant celle dudit orifice, 20 • enfoncer ladite rondelle sur ladite extrémité, ladite rondelle saillant axialement au delà de ladite extrémité, • disposer ledit complexe dans ladite cuve, • fermer ledit couvercle de sorte que ladite rondelle prenne appui sur la périphérie dudit orifice en créant une étanchéité dudit orifice par rapport 25 à la mousse, • injecter un mélange précurseur de mousse élastiquement compressible dans ledit espace de moulage, • après expansion de la mousse, démouler la matelassure 1 obtenue. Referring to the figures, there is described a method of producing a padding 1 of a motor vehicle, said padding comprising a coating complex 2 and a pad 3 of resiliently compressible foam padding, said complex comprising a lower sealing layer 4 to the foam overmoulded by said block, said sealing layer comprising a ventilation orifice 5 of the passenger, said block comprising a ventilation duct 6 opening on said orifice, said method comprising the following steps: • providing a mold comprising a tank and a cover defining a molding space of said padding, said cover comprising a pad 7 for molding said pipe, • providing a sealing washer 8 of elastically compressible material, said washer having a hole 9 of section similar to that of the end free of said pad and a peripheral envelope including that of said orifice, pressing said washer onto said end, said washer protruding axially beyond said end, • disposing said complex in said tank, • closing said lid so that said washer bears on the periphery of said orifice by sealing said orifice with respect to to the foam, • injecting a precursor mixture of elastically compressible foam into said molding space, • after expansion of the foam, demolding the padding 1 obtained.
30 Selon une réalisation, la rondelle 8 présente une portance moindre que celle du complexe 2, ceci permettant, dans le cas d'un complexe 2 d'épaisseur supérieure à son épaisseur nominale, comme le montre la figure 3b, un écrasement de la rondelle 8 en lieu et place d'un écrasement du complexe 2, ce qui supprime le phénomène de bossage localisé. According to one embodiment, the washer 8 has a lower lift than the complex 2, this allowing, in the case of a complex 2 of thickness greater than its nominal thickness, as shown in Figure 3b, a crushing of the washer 8 instead of a crash of the complex 2, which eliminates the phenomenon of localized boss.
Selon la réalisation représentée, la périphérie du trou 9 englobe celle de l'orifice 5 5, ce qui permet d'éviter une obstruction partielle dudit orifice par la rondelle 8 dans le cas où le plot 7 est un peu décalé par rapport à l'orifice 5, comme le montre la figure 3c. According to the embodiment shown, the periphery of the hole 9 includes that of the orifice 5 5, which makes it possible to avoid a partial obstruction of said orifice by the washer 8 in the case where the stud 7 is a little offset from the orifice 5, as shown in FIG. 3c.
Selon une réalisation, la rondelle 8 est à base de mousse. Selon la réalisation représentée, le plot 7 présente un palier 13 d'appui limitant l'enfoncement de la rondelle 8 sur l'extrémité libre 10. In one embodiment, the washer 8 is based on foam. According to the embodiment shown, the stud 7 has a bearing bearing 13 limiting the depression of the washer 8 on the free end 10.
Selon la réalisation représentée, le plot 7 présente une géométrie en tronc de 15 cône effilé vers son extrémité libre 10, ce qui facilite son démoulage. According to the embodiment shown, the stud 7 has a frustoconical geometry tapered towards its free end 10, which facilitates demolding.
Le palier 13 est en forme de couronne circulaire, sur laquelle vient prendre appui la rondelle 8. The bearing 13 is in the shape of a circular ring, on which the washer 8 comes to rest.
20 Dans le cas où le procédé s'applique à la réalisation d'une matelassure 1 dont la couche d'étanchéité 4 comprend une pluralité d'orifices 5 de ventilation, le bloc 3 comprenant une pluralité de conduits 6 de ventilation débouchant chacun sur un desdits orifices, ledit procédé peut utiliser, comme représenté en figure 2, une pluralité de rondelles 8 reliées entre elles par un pont de matière, 25 lesdites rondelles étant ici obtenues à partir d'une plaque 14 en matériau élastiquement compressible pourvue d'une pluralité de trous 9. In the case where the method applies to the production of a padding 1 whose sealing layer 4 comprises a plurality of ventilation orifices 5, the block 3 comprising a plurality of ventilation ducts 6 each opening on a of said orifices, said method can use, as represented in FIG. 2, a plurality of washers 8 interconnected by a bridge of material, said washers being here obtained from a plate 14 made of elastically compressible material provided with a plurality of of holes 9.
Une telle réalisation peut permettre de simplifier le montage des rondelles 8 qui sont parties prenantes d'une même pièce. On décrit à présent une matelassure 1 réalisée par le procédé sus décrit, ladite matelassure comprenant un complexe 2 de revêtement et un bloc 3 de rembourrage en mousse élastiquement compressible, ledit complexe 30 6 comprenant une couche d'étanchéité 4 à la mousse surmoulée par ledit bloc, ladite couche d'étanchéité comprenant un orifice 5 de ventilation du passager, ledit bloc comprenant un conduit 6 de ventilation débouchant sur ledit orifice, ladite matelassure comprenant en outre une rondelle 8 d'étanchéité, ladite rondelle étant surmoulée par la mousse dudit bloc et étant disposée à l'interface entre ledit orifice et ledit conduit. Such an embodiment can simplify the mounting of washers 8 which are part of the same room. We now describe a padding 1 made by the method described above, said padding comprising a coating complex 2 and a pad 3 of resiliently compressible foam padding, said complex 6 comprising a sealing layer 4 to the foam overmolded by said block, said sealing layer comprising a ventilation opening 5 of the passenger, said block comprising a ventilation duct 6 opening on said orifice, said padding further comprising a sealing washer 8, said washer being overmolded by the foam of said block and being disposed at the interface between said orifice and said conduit.
Selon les réalisations représentées, le complexe comprend en outre : •a une couche supérieure 10 de revêtement perméable à l'air, • une couche intermédiaire 11 perméable à l'air de diffusion d'air. According to the embodiments shown, the complex also comprises: • a top layer 10 of air-permeable coating, • an intermediate layer 11 permeable to air diffusion air.
Selon la réalisation de la figure 2, la matelassure 1 comprend une pluralité de rondelles 8 reliées entre elles par un pont de matière, lesdites rondelles étant obtenues à partir d'une plaque 14 en matériau élastiquement compressible pourvue d'une pluralité de trous 9. According to the embodiment of FIG. 2, the padding 1 comprises a plurality of washers 8 interconnected by a material bridge, said washers being obtained from a plate 14 of elastically compressible material provided with a plurality of holes 9.
